KONI is universally accepted as the leader in manufacturing high quality, adjustable shock absorbers. KONI shock absorbers are produced from the finest materials; surfaces are machined to the narrowest tolerances, and the strictest quality control standards are incorporated in all production steps. At the end of the production line every single damper is 100% dyno-tested to assure optimum performance. Because they are adjustable, KONI shocks can virtually last a lifetime.
